I guess you've already done it, so for all others...

I figured out the same :) My workaround is quite easy.

1) prepare everything at the host side (including the ./dfu-util )
2) "Set console to USB" and press "power"
3) asap Neo changes to "Press [AUX] to return to boot menu" fire the dfu-util 
command on host side

Note: Neo switches back to the "boot-menu" but as long as the host doesn't 
tell you anything different it should work :)
